This tool lets you quickly subnet IPv4 networks, visualise them, and split or join them with a single click. It also shows the address range, subnet mask, and number of hosts for each subnet. You can save and load your arrangement using bookmarks.

Thanks for creating this calculator. I didn't see any restrictions on use of the code so I put in a line attributing the original code to you. I did some minor modifications like embedding the images into the page so I could easily use it from a SharePoint site.
